Summary: This study investigated core crosslinked micelles based on poly(2-ethyl-2-oxazoline)-block-poly(n-butyl acrylate-co-d,l-homocysteine thiolactone acrylamide) by employing different di- and triamines and nucleophilic ring-opening reaction. The quantity of crosslinked micelle and free block copolymer was quantified by size exclusion chromatography (SEC), and the crosslinking conditions were optimized. Subsequently, micelles crosslinked with cystamine exhibited degradation times of 1.5 h to 5 h in the presence of dithiothreitol (DTT), depending on the composition of the hydrophobic core.

Summary: In this study, redox-responsive core-cross-linked (CCL) micelles were synthesized using diselenide (Se-Se) and disulfide (S-S) bonds, and their sensitivity to oxidation and reduction was compared. The micelles showed structural stability under physiological conditions but de-cross-linked in response to GSH and H2O2 treatments. DLS studies demonstrated that the Se-Se micelles were more responsive to changes in the redox environment compared to the S-S micelles. The developed micelles exhibited a pH-dependent drug release and showed cytotoxicity against cancer cells while remaining non-toxic to normal cells.

Summary: A nanoparticle system targeted at luteinizing hormone-releasing hormone (LHRH) receptor and responsive to the tumor microenvironment has been developed for selective delivery of chemotherapeutic drugs to triple-negative breast cancer (TNBC) cells. This system shows high drug loading efficiency, receptor-mediated internalization into TNBC cells, and improved cytotoxicity compared to non-targeted counterparts. In vivo studies demonstrate enhanced tumor distribution and penetration of payloads, leading to superior therapeutic efficacy in TNBC models. These results offer new insights into precise drug delivery for TNBC treatment.

Summary: A covalent organic framework (COF) sonosensitizer is developed using a new nanoscale COF preparation strategy, which improves the therapeutic effect of sonodynamic therapy (SDT). The COF structure prevents aggregation of the sonosensitizer molecules and enhances their chemical stability. Additionally, the coordination of Fe3+ to COF enables chemodynamic therapy performance and glutathione consumption ability. The combination of enhanced SDT and alpha-PD-L1 antibody achieves effective antitumor effects.

Summary: The immune checkpoint blockade (ICB) has a low response rate in clinical cancer treatment. Chemotherapy can enhance the response rate of the ICB, but it leads to side effects. Loading chemotherapy drugs through nanocarriers can reduce off-target toxicity. In this study, researchers developed doxorubicin (DOX) nanoparticles (DOX NPs) loaded in a polymeric carrier that was responsive to the tumor microenvironment (TME). However, a combination therapy of DOX NPs and ICB induced tumor adaptive resistance, which was found to be caused by TGF-beta 1. To overcome this resistance, an immune cocktail therapy containing DOX NPs, ICB, and TGF-beta 1 gene silencing nanoparticles was developed, successfully reversing the immunosuppressive TME and improving tumor treatment efficiency.
